People with Severe Vision Loss are Less Likely to Accurately Judge Distance of Nearby Sounds

A new study shows that greater severity of vision loss is associated with increased auditory judgments of distance and room size.

on average, participants with severe visual losses perceived sounds to be twice as far away, and rooms to be three times larger, than sighted controls; distance estimates for sighted controls were most accurate for closer sounds and least accurate for farther sounds; however, as the severity of visual impairment increased, accuracy decreased for closer sounds and increased for farther sounds. read more

Study Shows Blind People Need Temporal Information to Detect Location of Sounds

A new study supported by the EU-funded weDRAW project has shown that the deficit disappears if congenitally blind individuals are presented with coherent temporal and spatial cues.

The popular belief is that blindness enhances other senses such as hearing. Several studies show that while blind people’s other senses are not more acute, they do use auditory modality as a substitute to interpret some spatial representations. However, auditory precision might be impaired in congenitally blind individuals performing an audio-space bisection task. The findings were recently published in the journal iScience. read more
